Uma análise dos fatores aerodinâmicos e das causas estruturais nos acidentes causados pelo vento em edificações

Abstract

Accidents in buildings due to wind action occur frequently and, in most cases, are attributed to uncommon winds when, in fact, the causes are other. Annually, although the number of events of this nature is large, most of them are not publicized, and either origin investigated. This work deals with the studies on aerodynamic factors and structural causes in accidents caused by wind in structures. The methodology used was an individual discussion of the influence of aerodynamic aspects. In addition, aerodynamic analysis of the buildings during the construction process. Also, were studied the neighborhood effects on the mean wind loading. Likewise, another possible cause of accidents due to wind in the structures analyzed in this work was the reforms in the construction. Finally, the structural causes of wind collapse in edifications, focusing on design errors. This study may guide the elaboration of a guide to identifying project risks, mitigating them, and even eliminating the adverse effects caused by the action of the wind on the buildings.
